Specification of Letters Patent.

Patented Dec. 26, 1905.

Application filed May 10, 1905. Serial No. 259,807.

To all whom it may concern:

Be it known that I, CoNs'rANTIN VLADIMIRO- VITOH VON NoLLn, a subject ofthe Emperor of Russia, and a resident of Odessa, Russia, have inventedcertain new and useful Improvements in Devices for Connecting the UpperParts of Cars with WVheel-Frames, of which the following is aspecification.

This invention relates to a device for connecting the body of carriagesof every description with their wheel-frames, without diminishing theelasticity or resiliency of the body on the frame.

The peculiar feature of the invention consists therein that the upperframe of the carriage does not rest, as hitherto, immediately andwithout any intermediate link or parts on an elastic material carried bythe lower frame or on spiral or plate springs or is suspended on thefree ends of the latter, but is suspended on the ends of rigid or stiffone or two armed levers turning on horizontal pivots of the underframeand of which each rests against an elastic pad or cushion at one side orthe other or on both sides of a pivot, the distance of this supportingor resting point from that pivot being smaller than the distance of theworking point of the load from that pivot.

On the drawings are illustrated two constructions based on this process.

Figure 1 shows a side View of a construction without any load on thecarriage and Fig. 2 with a loaded carriage and the body of the carriagesuspended on one-arrned levers,while in the construction shown in Fig. 3two-armed levers are used.

Similar letters refer to similar parts throughout the several views.

In both cases the stiff levers b,intended to receive the frame 0 of thecarriage-body, turn on pivots a, which are rigidly fastened in thewheel-frame (Z of the carriage. Each of these levers 6 passes over asegment-piece 6, arranged concentrically with its pivot a and of acircular cross-section, which segment rises out of the middle of a disk2', rigidly fastened to the underframe of the carriage, while its upperend is journaled in the middle of a tie or band 70, which is likewiseheld by the underframe, or said band forming the connectingpiece betweentwo guiding-segments. The part f of the lever which passes over theguiding-piece 6 forms a circular eye, the surface of which facing thedisk 2' is of the diameter of that disk, and the opposite surface issimilar to that of the band in. Both faces of this eyef and also thoseof the disk t' and of the band Zclie in planes directed radially towardthe center of the pivot. Over the part of the guidingsegment 6 lyingbetween the band and the eye f of the lever a is pushed a disk It, of anelastic material, preferably india-ru bber, and over the part betweenthe eye and the disk 2' is placed a sulficiently-large number oflikewise elastic disks 9, so that when there is no pressure or load onthe lever a the space between the said parts is completely filled up andthere is a slight pressure on the disks, Fig. 1. When the upper part ofthe carriage is loaded, these disks 9 are further compressed, Fig. 2,and form a cushion which weakens all the shocks transmitted from theunderframe of the car riage to the upper frame, the efliciency of whichcushion depends on the elasticity of the india-rubber used or thetension of the spiral springs used instead of the latter and can byselecting a suitablematerial always be adapted to the requirements. Thethus-formed elastic cushion is used with one-armed as well as two-armedlevers and applied in both cases in places lying between the axis ofrotation and the working point of the load. In the case of two-armedlevers, especially if the carriage is heavily loaded, two cushions canbe put in, one on one side and the other on the other side of pivot aand at the same distance from it, Fig. 2. The suspension of the load onthe upper ends of the leverv is effected in the usual manner; but alsoin this case one of the above-described elastic or spring devices may beused to obtain also at this point a spring action. At a certain distancefrom the bolt 0, which unites the lever F) with a shoe Z, adjusted, bymeans of cross-bolts n, in holes m along the frame 0 of thecarriage-body, there is placed an india-rubber cushion p between theshoe and the lever 5, provided at this point with a circular eye 8,which cushion is held by the segment-piece 1" and is compressed when theframe 0 is loaded, while an elastic disk q is placed before a band 6,fastened to the end of the segment-piecer, against which disk pressesthe lever b when the frame is loaded.

This invention is in the first place intended to connect the upper framewith the wheelframe of vehicles used for transporting light loads onload roads; but it can also be used for all other vehicles whenever itis desirable or necessary to reduce all shocks to which the underframeis subjected, and consequently,

ICC

besides for automobiles and other heavy vehicles, also for sledges, forstretchers and ambulance-carts for the sick and Wounded, for beds and soon used on ships and railway-cars and Will be found to be superior tothe constructions now in use for such cases.

What I claim as my invention, and desire to secure by United StatesLetters Patent, is-

1. The combination with avehicle-body and truck or Wheel frame, of aninclined lever or arm pivotally connected to said Wheel-frame, and tosaid vehicle, springs tending to yieldingly hold said lever or arm in aninclined position and a segment-piece supporting said springs.

2. The combination With a vehicle-body and truck or Wheel frame, of aninclined lever or arm pivotally connected to said Wheel-frame and tosaid vehicle, a segment-piece on the frame, a guiding-eye connected tothe lever e and having sliding movement on the segmentpiece and springson the segment-piece upon Which the eye rests.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing Witnesses.
